Abstract

The utility model provides an inflatable life jacket comprising an air bag (13) and an air charging device made up of a compressed air tank, an inflation valve and a switch component, wherein, the air bag is provided with sleeves, with which the air bag forms clothing, a left air bag piece and a right air bag piece are in contact with each other at the edge in the middle of the front opening, the parts making up the air bag are communicated with each other, thin canvas clothing is arranged on the outside of the clothing-shaped air bag as an outer layer (12), a slide fastener (11) is installed between the left and the right pieces of the front opening of the outer layer, the air charging device is mounted on the outside of the thin canvas clothing, and the air pipe of the air charging device is connected with the air bag. The inflatable life jacket provided by the utility model is characterized by not only the clothing-shaped air bag provides buoyancy, but also a layer of thin canvas clothing is arranged on the outside of the air bag, which can force the air bag to swell towards a human body. Compared with the prior art, the utility model is superior in that the inner layer of the air bag, when inflated, can be ensured of being closely attached to the human body, with water not being allowed to flow through the surface of the human body unless through underwear fibers, thereby reducing the risk of water carrying away the energy of human body, improving the capability to preserve heat, and greatly prolonging the survival time of people falling into water.

Description

Inflatable lifejacket

Technical field the utility model relates to a kind of inflatable lifejacket, life technical field in the water of the equipment relevant with ship in the genus transportation.

The background technology life jacket is the crewman, personnel waterborne such as operator fall into water or the equipment in order to ensure when having to abandon carrying equipment meeting accident on hand.At present the most frequently used life jacket is the vest formula life jacket of being made by buoyant material that constitutes with the front and back buoyancy bag, but because the big alerting ability that hinders one's work of this life jacket volume.For not hindered in the assurance work, common personnel waterborne do not wear at any time but wear when emergency situation takes place temporarily, and this has increased drowned danger.Some need interim gas filed inflatable lifejacket of time spent all the more so.For this reason, there is Chinese utility model patent ZL200520132008.X " emergency pneumatic life jacket " to introduce the inflatable lifejacket of a kind of " can be used as at ordinary times on one's body vest is through; during emergency situation ... inflation ", " can be the gas filled device that the life jacket fast aeration is made of compression gas tank, charge valve and switch block " arranged on it.This life jacket has solved the deficiency that can not use life jacket fast.But because all life jackets all are to be target so that buoyancy to be provided, and big gap is arranged between the health, more have only thoracic dorsal two parts, in fact the drowning people is immersed in the water from head to foot, and body temperature runs off very fast.Therefore the drowning people have considerable part to be because before being rescued in water the time too many and die from hypothermia.

Summary of the invention is at above-mentioned foot, and the utility model will provide a kind of can in case of emergency the inflation to become life exactly, can effectively keep the inflatable lifejacket of drowning people's body temperature again.

The inflatable lifejacket that the utility model provides, the gas filled device that air bag is arranged and constitute by compression gas tank, charge valve and switch block, said air bag has the back front part of a Chinese robe or jacket, sheet about being divided in the middle of the front part of a Chinese robe or jacket, air bag also has sleeve and becomes garment shape, about the limit of sheet air bag in the middle of the front part of a Chinese robe or jacket contact, be communicated with between the air bag each several part, thin ducks is arranged for outer outside the air bag of garment shape, between the sheet slide fastener is installed about the outer front part of a Chinese robe or jacket, outside thin ducks gas filled device is installed, the tracheae of gas filled device is connected with air bag.

The inflatable lifejacket that the utility model provides, the air bag that buoyancy is provided is made into the garment shape of sleeve, and the clothes that outside air bag, has one deck to make of thin canvas, thin canvas is that the lining that is used to make jean has bigger elastic force, can not relax, can force air bag to expand to the health direction because of drawing to stretch tight; Two limits in the middle of the front part of a Chinese robe or jacket contact about air bag simultaneously, but this contact position is subjected to outer constraint mutual extrusion to reach the purpose of shutoff water behind the inflation.Compared with prior art, the utility model is adjacent to close mutually at inflation rear gasbag internal layer and health, the body surface of can not flowing through in a large number except that infiltrating by the underwear fiber has reduced the water band from body energy, improve insulating power, can prolong drowning people's survival time greatly.

The inflatable lifejacket that the utility model provides, its waist and coat-sleeve mouth tighten up, and gas filled device is installed on the low back position, can make life jacket can not hinder operation at ordinary times.

The inflatable lifejacket that the utility model provides, said air bag also is connected with the air bag of trousers shape at waist, and the also thin ducks outside waist is connected with the air bag of trousers shape of said skin, cracking down to crotch portion about the air bag front part of a Chinese robe or jacket between the sheet, the slide fastener about the outer front part of a Chinese robe or jacket between the sheet is also down to crotch portion.Make inflatable lifejacket become the form that clothing link to each other.

The trouser opening of said trousers tightens up, and can make life jacket can not hinder operation at ordinary times.

Paste mutually with skin with trouser opening place internal layer with cuff at neckline behind the said airbag aeration, make the utility model can completely cut off contacting of body surface and water basically fully, further improve insulating power, increase the survival time of drowning people in water in running condition.

Said air bag and outer punishment at waist are slit into upper garment and trousers two parts, so that use flexibly, gas filled device has two, is connected with the air bag of garment shape or the air bag of trousers shape separately, and perhaps gas filled device has two outlets to connect the air bag of garment shape or the air bag of trousers shape simultaneously.
